Abstract
A fault tolerant machine drive based on permanent magnet assisted synchronous reluctance machine (PMA SynRM) is proposed and investigated for applications where reliability and safety are crucial. In order to achieve enhanced fault tolerant capability, the risk of permanent magnet field that cannot be turned off under fault conditions is minimized without compromise in torque density and efficiency. This is achieved by employing a synchronous reluctance rotor topology with embedded permanent magnets. Three independent, segregated 3-phase windings are configured to ensure isolation and non-overlapping between the three 3-phase winding sets. Each 3-phase winding set is driven by a standard 3-phase inverter to facilitate fast integration and cost reduction. The machine behavior under various fault conditions has been evaluated by finite element (FE) simulations. A 40kW prototype was designed, constructed and tested. The test results demonstrate the performance and excellent fault tolerant capability of the proposed drive system under various faults, including open circuit and short circuit conditions.
